CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims the priority benefit of U.S. provisional patent application No. 61/738,004, filed Dec. 17, 2012, the disclosure of which is incorporated by reference.

TECHNICAL FIELD

The application relates generally to training and physiotherapy devices and, more specifically, to devices for training swimmers, performing physiotherapeutic exercises, and learning to swim, and units for measuring parameters of swimmers.

BACKGROUND

The approaches described in this section could be pursued but are not necessarily approaches that have previously been conceived or pursued. Therefore, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.

One of the approaches for treating spinal disorders involves straightening the vertebral column supported by spinal muscles. It is a well-established fact that swimming provides for rehabilitation with few contraindications of persons having spinal disorders. Swimming is also an optimal training exercise for people of any age. These are some of the reasons why pools are very popular.

When teaching persons to swim, training swimmers, or performing physiotherapeutic exercises with persons having spinal injuries or disorders, it is important to create pool conditions that allow the swimmer to feel comfortable. Traditional pools intended for simultaneous training of several persons do not allow adjusting the conditions in the pool to the needs and preferences of each person.

Furthermore, it is important to register the physical parameters of the person during swimming. Such parameters may be used for selecting a swimming or therapeutic program for the swimmer. Traditional pools do not allow monitoring the swimmer and registering physical parameters of the swimmer during physical activity in the pool.

The present disclosure relates to a device for training swimmers, performing physiotherapeutic exercises, and learning to swim suitable for performing physiotherapeutic exercises for persons having orthopedic injuries or disorders. The orthopedic injuries or disorders may include spinal curvature, herniation of intervertebral disk, post-surgical rehabilitation, and so forth.

The compact size of the device for learning to swim, training swimmers, and performing physiotherapeutic exercises allows locating the device in relatively small premises. The device for learning to swim, training swimmers, and performing physiotherapeutic exercises may be disposed at any location, such as in hospitals, in schools, in swimming training centers, in gym locations, in office buildings, in rehabilitation centers, and even at home.

The device for training swimmers and performing physiotherapeutic exercises comprises a tank and a cover. The size of the tank is sufficient to accommodate a swimmer. The cover is configured to close the tank so as specific air and water conditions can be set inside the device for training swimmers and performing physiotherapeutic exercises. The device for training swimmers and performing physiotherapeutic exercises further comprises a regulating unit for controlling conditions inside the device. Therefore, the conditions inside the device for training swimmers and performing physiotherapeutic exercises are monitored and can be adjusted according to preferences of the swimmer or medical indications prescribed for the swimmer by a doctor. The device for training swimmers and performing physiotherapeutic exercises further comprises a display unit. The display unit may be located inside the device for training swimmers and performing physiotherapeutic exercises so that the swimmer can see the display unit during swimming.

The unit 300 for measuring parameters of a swimmer is connected to the device 200. The connection may be permanent or use fixing elements. The swimmer 120 is located inside the device 200 and connected to the unit 300 for measuring parameters of a swimmer. The unit 300 for measuring parameters of a swimmer collects and processes the parameters of the swimmer 120. The swimmer 120 represents a person in need of swimming training, learning to swim, performing physiotherapeutic exercises, and so forth. The unit 300 for measuring parameters of a swimmer transmits the processed parameters of the swimmer 120 to the peripheral unit 130. The peripheral unit 130 includes a mobile telephone, a personal computer (PC), a tablet PC, a laptop, a smartphone, a monitor, any personal digital device of the swimmer or any digital device in a location of the device 200 for training swimmers and performing physiotherapeutic exercises, and so forth.

FIG. 2A shows a simplified perspective view of the device 200 for training swimmers and performing physiotherapeutic exercises. The device 200 comprises a tank 205 configured to accommodate a swimmer 120. The tank 205 may have sufficient dimensions so as to allow the swimmer 120 to execute normal swimming strokes. The tank 205 may be of any shape, such as round, rectangular, square, pear-shaped, and so forth. The tank 205 may be made of any material. In some embodiments, the tank 205 is transparent or partially transparent.

As shown on FIG. 2A, the device 200 comprises a cover 210 connected to the tank 205. The cover 210 may be configured to open completely or open partially, and may be removable, slidable, flippable, or any further type. The cover 210 may be configured as one part, or the cover may consist of several parts. The cover 210 is made of any suitable material. In some embodiments, the cover 210 is transparent or partially transparent. In FIG. 2A, the cover 210 of the device 200 is shown in a closed state. FIG. 2B shows the device 200 with the cover 220 in an open state. The cover 210 is configured to open to such an extent that the swimmer 120 can freely move in or move out the device 200.

Referring back to FIG. 2A, the swimmer 120 can be connected to the device 200 by a restraining element 215. The restraining element 215 has a first end and a second end. The restraining element 215 is connected on one end to the swimmer 120 via a harness 220, such as ankle harness, a leg harness, a thigh harness, a pelvis harness, a waist harness, a chest harness, a neck harness, a head harness, an arm harness, a shoulder harness, a wrist harness, and a body harness, and the like. A waist harness 220 is shown on FIG. 2A. The restraining element 215 may include a tether, a cord, a rope, a resilient member, such as a resin or a spring-loaded mechanical expander, and the like. Another end of the restraining element 215 is connected to one of the tank 205 and the cover 210 of the device 200. Thus, the restraining element 215 connected to the swimmer 120 allows the swimmer 120 to stay in a relatively stationary position during swimming. In such a way, in-place swimming may be enabled. When the swimmer 120, being connected to the device 200 by the restraining element 215, performs the swimming strokes, a resistance force occurs and the spine of the swimmer 120 stretches. The horizontal stretch of the spine of the swimmer allows the vertebrae to come to their natural position.

With continuing reference to FIG. 2A, another end of the restraining element 215 may be connected to the tank 205 or the cover through a unit 300 for measuring parameters of the swimmer. The unit 300 may be attached to the tank 205 or the cover 210 of the device 200. The unit 300 may be provided for measuring characteristics of the swimmer 120 during swimming and may be located on any side of the tank 205 or the cover 210 of the device 200. In an example embodiment, the unit 300 can be used for measuring parameters of the swimmer moving in any water reservoir. The water reservoir includes the device 200, a water tank, a pool, a bath, a surface water body, an indoor water park, an artificial water reservoir, and the like.

The housing 305 may be of any suitable shape, such as rectangular, round, spherical, and the like. The housing 305 may be made of any suitable material, such as plastic, metal, ceramics, and the like. The unit 300 further comprises a motive force sensor 310 configured to measure a motive force associated with the swimmer. The motive force is generated by the swimmer moving in a water reservoir, such as a device for training swimmers and performing physiotherapeutic exercises as shown on FIG. 2A.

In such a way, the restraining element is able to transfer the motive force from the swimmer to the motive force sensor 310. The motive force sensor 310 measures the motive force of the swimmer based on a tensile force acting on the motive force sensor 310 through the restraining element. In an example embodiment, the motive force sensor 310 includes one or more of a piezo sensor, a strain gauge, and any sensor able to measure the motive force of the swimmer.

In an example embodiment, the unit 300 is permanently attached to the water reservoir. In a further example embodiment, the unit 300 optionally comprises one or more fixing elements 330.

FIG. 10 shows a scheme of a system 1000 of two or more devices 200 for training swimmers combined into a group, in accordance with an example embodiment. The described system 1000 of devices 200 for learning to swim, training swimmers, and performing physiotherapeutic exercises is capable of providing the swimmers with services without any assistance from staff in a place where the system is located, with automatic access to the devices for training swimmers and performing physiotherapeutic exercises and with remote monitoring and controlling of the training of the swimmer. The system 1000 of devices 200 may be located in a swimming center on the ground floor of an office building. For the group of devices 200, one communication unit 1005 is provided. The communication unit 1005 is capable of collecting and storing the individual data of each swimmer, automatically setting the modes for each swimmer in accordance with the stored personal data of each swimmer, maintaining the connection of the swimmer in each of the devices 200 with his personal trainer or doctor, synchronizing the operation of units for regulation of the conditions for each particular device 200, and the like. Thus, each device 200 is completely individualized for each swimmer. The communication unit 1005 includes a PC, a tablet PC, a monitor, a touch screen device, and like devices located in the swimming center.

The swimmer 1010 who wants to practice swimming visits the swimming center for the first time. An administrator (not shown) of the swimming center registers the swimmer 1010, and the swimmer 1010 may select a swimming program and conditions inside the device 200 suitable for the swimmer 1010. The information about the swimming program and conditions chosen by the swimmer 1005 is stored in a communication unit 1005. The swimmer 1010 is given a pass or an access code by the administrator. If necessary, the swimmer 1010 visits a doctor or a trainer for consultation as to which program is suitable for the swimmer 1010. Then the swimmer 1010 goes to the device 200 assigned to the swimmer 1010 by the communication unit 1005. The swimmer 1010 inputs the pass or the access code into the communication unit 1005. The information about the swimmer 1010 and the training program is already stored in the communication unit 1005. Therefore, after identification of the swimmer 1010, the communication unit 1005 sets the swimming program in accordance with the personal data of the swimmer 1010. Furthermore, the communication unit 1005 sets the conditions inside the device 200 assigned to the swimmer 1010 in accordance with the personal data of the swimmer 1010. Then the swimmer 1010 goes to the device 200 indicated by the communication unit 1005, puts on a harness 1015 connected to a restraining element 1020 on his waist or legs and enters the tank of the device 200. Once the swimmer 1010 is inside the tank, the cover of the device 200 may close, and the swimmer 1010 start training. The swimmer 1010 sees the exercises he should perform during training displayed on a display unit on the bottom of the tank of the device 200. If the swimmer 1010 performs the exercise incorrectly, a notice may be shown on the display unit (for example, to increase speed or intensity of swimming). In an example embodiment, the trainer or the doctor monitors the training of the swimmer 1010 online and gives instructions to the swimmer 1010. The swimmer 1010 may hear the voice of the trainer or the doctor inside the device 200, or the instructions may be shown on the display unit on the bottom of the tank of the device 200. When the time of the training is over, the swimmer 1010 sees the corresponding notice on the display unit, finishes training, removes the harness 1015, and exits the device 200.

In an example embodiment, the next time the swimmer 1010 comes, the swimmer 1010 needs only to input the pass or access code into the communication unit 1005, and the parameters of training and conditions are set automatically inside the device 200 in accordance with the stored personal data of the swimmer 1010. In case the swimmer 1010 needs additional consultation from the trainer or the doctor, the swimmer 1010 contacts the trainer or the doctor via the communication unit 1005 at any time during the training.

Furthermore, in order to avoid queues, in cases when the swimmer comes to have the training and all the devices for learning to swim, training swimmers, and performing physiotherapeutic exercises are unavailable, the swimmer may choose a time of training suitable for the swimmer. The chosen time is included in the personal data of the swimmer and stored in the communication unit, and one of the devices for learning to swim, training swimmers, and performing physiotherapeutic exercises is reserved for the swimmer at his specific time. Furthermore, in an example embodiment, the pass or the access code of the swimmer is configured not to allow the swimmer to have access to the device for learning to swim, training swimmers, and performing physiotherapeutic exercises at a time outside of his reserved time.

In the system 1000, a regulating unit for controlling conditions inside the device, such as an air conditioning unit, a unit saturating the air with fragrances and gas additives, a temperature regulation unit, a water cleaning unit, a water salinity regulation unit, and the like, is used to simultaneously regulate the conditions of the group of devices 200. Furthermore, the conditions set in each device 200 may be different. In other words, in case of the group of devices 200, the quantity of the regulating unit for controlling conditions inside the device may be optimized to provide economical advantage.

Thus, various systems and methods for training swimmers and for measuring parameters of a swimmer have been described.
